Why the study?

Patients with chronic heart failure exhibit microcirculation alterations and endothelial dysfunction, but little is known about the acute systemic effect of exercise on peripheral muscle microcirculation.

Does an acute respiratory exercise bout improve peripheral microcirculation in patients with chronic heart failure?

Population

Thirty-four stable CHF patients

Comparison

Microcirculation immediately after a respiratory exercise program vs at rest

Follow-up

Immediately after the respiratory exercise program

Discussion

Member takes

Implication

May suggest acute systemic microcirculatory effects from respiratory exercise in CHF; leaves open clinical relevance.

Structured PICO

Does an acute respiratory exercise bout improve peripheral microcirculation in patients with chronic heart failure?

Population

34 stable chronic heart failure (CHF) patients, mean age 61.4±9.2 years, 30 male/4 female, ejection fraction (EF) 33.9±7.8%, NYHA class ≥ II.

Intervention

Acute respiratory exercise bout (5 sets/10 repetitions, training load: 60% of maximal inspiratory pressure).

Comparator

Baseline (rest) prior to the exercise bout.

Outcome

Microcirculatory indices including reperfusion rate (RR), oxygen consumption rate (OCR), and basal tissue oxygen saturation (StO2) measured by near-infrared spectroscopy (NIRS) at the thenar muscle immediately after exercise.surrogate

An acute bout of respiratory muscle exercise significantly improves dynamic microcirculatory indices in non-exercising peripheral muscles of patients with chronic heart failure.
